1) MATLAB “disttool” enable us to see the influence of parameter changes on the shapes of the pdf and cdf. However, there is a limited number of distributions supported by this tool. How can I observe the changes of pdf and cdf for the rest of the distributions which are not supported by "disttool"?


2) MATLAB “random” function enable us to generate the random numbers as per the probability distribution. This function also only supported a limited number of distributions. How can I generate the random numbers for the rest of the distributions which are not supported by "random" number?

can you name a couple of distribution you are interested in, that is not supported.. and of course, I am assuming you have MATLAB statistical tooobox
